We like this postcard for several reasons, maybe not corresponding to yours, but here are ours anyway:  (1) it’s a lottery card issued by China Post, with the (2011) number stub still attached; (2) it has two other, different, real stamps adjacent to the pre-printed one; (3) readable postmark; and (4) it’s just a very busy “local view” card.  Mailed in 2012.  Grade: 1
